Nvidia's cloud computing clients must now sell at least 51% of their services to non-Chinese companies, the FT reported, citing five people with knowledge of the matter.

The new rules only affect future contracts and not existing agreements, the report said.

Nvidia neither confirmed nor denied the report to AFP, but said in a statement that "datacenters and clouds built on American chips are the foundation that American model and application makers need to compete worldwide."
